A photo with perhaps the highest resolution of any image ever captured of Machu Picchu has been posted online.

At 15.9 gigapixels (one gigapixel is equivalent to 1000 megapixels), the image of the Inca citadel allows viewers to see the site in impressive detail.

The online image was taken using a Canon 7D with a 400mm lens. It actually consists of 1,920 pictures taken using a robotic camera mount, which were then stitched together. The photographer was Jeff Cremer, the photo tour director of Rainforest Expeditions, a tour operator that specialises in trips to Peru. He believes his image is the highest resolution picture of the World Heritage site that has ever been taken.
